摘要: A fine grained metal composition suitable for forming in a partially solid, liquid condition. The is prepared by producing solid having an essentially directional grain structure and heating the to temperature above solidus below liquidus produce mixture containing at least 0.05 volume fraction liquid. composition, prior heating, has strain level introduced such that upon comprises uniform discrete spheroidal particles contained within lower melting matrix. heated alloy then solidified while condition, uniform, microstructure.
